Subject: [PATCH -next] powerpc/book3s64: Make some symbols static

Fix sparse warnings:

arch/powerpc/mm/book3s64/radix_pgtable.c:326:13: warning: symbol 'radix_init_pgtable' was not declared. Should it be static?
arch/powerpc/mm/book3s64/hash_native.c:48:1: warning: symbol 'native_tlbie_lock' was not declared. Should it be static?
arch/powerpc/mm/book3s64/hash_utils.c:988:24: warning: symbol 'init_hash_mm_context' was not declared. Should it be static?
